After crossing over to the Demon High School world and mingling in it for a thousand years, Shen Aliog received an invitation to a dimensional chat dress when he became the Fifth Demon King of the Underworld.
Out of boredom, Shen Aliog chose to accept.
[Cang Yue: Welcome newcomer!] I’m the highest combat power in the entire dress.
[Aisders, Nonsense!] I’m the highest combat power in the entire dress.
Snow of Snow: Good newcomer! As an ordinary person, I’m shivering in fear between two big shots!
[Fourth Palace Bright Night: 1]
“…………”
"Thank you for the invitation! A man in hell has just become a demon king: I have official business to do, so I’ll hide for the time being.”
